3 Description

The ADC3661, ADC3662, and ADC3663 (ADC366x)

family of devices are low-noise, ultra-low power, 16-

bit, 10-MSPS to 65-MSPS, high-speed, dual-channel,

analog-to-digital converters (ADCs). Designed for low

noise performance, these devices deliver a noise

spectral density of –158 dBFS/Hz combined with

great linearity and dynamic range. The ADC366x

offers good dc precision together with IF sampling

support making these devices suitable for a wide

range of applications. High-speed control loops

benefit from the short latency as low as only 1 clock

cycle. The ADC consumes only 94 mW/ch at 65

MSPS and power consumption that scales well with

lower sampling rates.

The ADC366x uses a serial LVDS (SLVDS) interface

to output the data. The devices support a two-lane,

a one-lane and a half-lane option. These devices are

a pin-to-pin compatible family with 16-bit and 18-bit

resolution and different speed grades. The devices

come in a 40-pint QFN package (5 x 5 mm), and

supports the extended industrial temperature range of

–40°C to +105⁰C.
